CNB: A critical-network-based timing optimization method for standard cell global routing

A novel method, named critical-network-based (CNB) for timing optimization in global routing is presented in this paper. The essence of this method is different from that of the typical existing ones, named nets-based (NB) and critical-path-based (CPB). The main contribution of this paper is that the CNB delay reduction method is more efficient than the… (More)
